Remote control white LED fixture

[gibbothegreat]

Hi folks,

 

have spent hours on the web trawling through this and not made great progress, so wondering if anyone here can come up with a suggestion for a suitable product to meet the following requirements:

 

must be LED

Warm White preferred (as opposed to colour mixing units)

must be remote controllable - IR preferred, as for the most part the users will be highly non-technical.

 

The background to this is that I am needing to replace 2 x P137 floods fitted with PAR38s with something that will do the same job but has the ability to be the same level for general use and considerably brighter when needed. The church have specified that anything new fitted has to be low-energy, access is very tricky so the long life of LED is very attractive, and it needs to be remotely controlled - the P137s are currently hard-wired via spurs to switches at the back of the church.

 

There are plenty of colour units fitted with remote facilities, either via IR or wireless DMX, but I haven't yet found a white only one. My feeling is that the colour rendering and 'no glasses 3D' effect of RGB mixing plus the requirement for considerable brightness makes colour mixing units not ideal, but I'm open to correction/suggestions on that too.

Hi Ian,

 

Welcome to the Blue room,

 

Spotlight have a couple of options, in the Mini LED Range that might meet your requirements.

The RGB Mini LED fixture is a 15W Tri colour fixture, that does have the IR Remote, to select both colour and Intensity, as well as DMX control.

and a 15W Warm White Mini LED, but this is a DMX only Fixture.

Details on both units can be found here Spotlight's Website

 

Any questions, please feel free to give me a call.

 

Many thanks

Many thanks Paul, will take a look at those. --EDIT-- Actually, that looks just the job, do you know where these can be purchased in the UK?

dont know your budget, but have a look at pulsars offerings

 

PULSAR

 

they do quite a range, their crab may be of interest to you, their stuff goes back to propriatry controller, of which Im sure there is an IR one in there somwhere.

 

as for RGB fixtures, the pulsar tricolour stuff is good, basially and Red, green and blue emitter in one spot, so it eliminates the colour hue effect you get from seperate rgb emmiters.

they do also do plain white, which IIC is controllable to the "colour" of white you get.

 

not sure on their range, but it might also be worth looking at thomas

What is the current control system?

I would guess that it's light switches or relays right now?

 

Is dimming required, or do they actually only need something that does 'Off', 'Normal' and 'Bright'?

 

If dimming is not required I would suggest HID fixtures rather than LED.

- LED is not very bright unless you spend a lot of money on units with lots of high-wattage diodes, and they consume power even when 'off'.

- CDM discharge lamps have >10,000 hour lifetime - that's five lamps to give the same 'rated lifetime' as an entire LED fixture - and consume no power when turned off.

 

You can also control discharge fixtures using normal light switches or relays (assuming suitable current rating), so you may be able to use the existing controller.

 

Downside to discharge is that they are not instant-on - CDM will arc almost instantly, but takes a few minutes to reach full brightness.

Thanks both. It is indeed plain anilla light switches at present. Requirement is, as you've devined, basically 'off-normal-bright' Hadn't thought of HID, but they might indeed fit - will investigate options. WIll check out Pulsar's and Thomas' range s too.

 

Cheers,
